以下是引用xiebinustc在2004-11-16的发言:刚才做的feifei逻辑,13/18,感觉似乎比og难一些.还是超时的很厉害. 下面这题没法理解...请大家帮忙解答 feifei23 23. On a certain day, nine scheduled flights on Swift Airlines were canceled. Ordinarily, a cancellation is due to mechanical problems with the airplane scheduled for a certain flight. However, since it is unlikely that Swift would have the mechanical problems with more than one or two scheduled flights on a single day, some of the nine cancellations were probably due to something else. The argument depends on which one of the following assumptions?
A. More than one or two airplanes were scheduled for the nine canceled flights. B. Swift Airlines has fewer mechanical problems than do other airlines of the same size. C. Each of the canceled flights would have been longer than the average flight on Swift Airlines. D. Swift Airlines had never before canceled more than one or two scheduled flights on a single day. E. All of the airplanes scheduled for the canceled flights are based at the same airport.
参考答案:A 采用取非法。
思路:否定More than one or two airplanes were scheduled for the nine canceled flights.将削弱作者的结论。
A:取非削弱
B:无关。
C:无关。
D:无关。
E:无关。

组长, 如果你坐过东方航空的国际航班,就知道nine scheduled flight的意思了,一个航班可以被无数次更改时间,或登机口... 所以,看了这题,我的第一反应就是选A。 |
